Turkey has shot down a very small Russian drone that crossed its border. I cannot imagine that an F-16 did the shooting because the drone is far, far too intact for that given its size.
Russia has hit over 380 targets since the start of their campaign approximately 2 weeks ago. Putin is claiming hundreds of rebels have been killed in support of Assad.
Russian thermobaric rocket artillery has been spotted in Syria now too.
Russia has stated it may start firing missiles from its Mediterranean flotilla against the rebels.
